Lecture Notes: Social Psychology, Consciousness, Developmental Norms, and Life Milestones

Social psychology studies how we function in social environments.
It examines how we create memories and how we think about ourselves and others.
It encompasses the scientific study of consciousness: being present in the moment and perceiving your brain’s minute-by-minute experience.
The brain constructs a continuous, minute-to-minute (millisecond-scale) experience for you.

People are each slightly different in perception; the classic question: "Is my red your red?"—impossible to determine someone else’s exact conscious experience.
Because consciousness is inherently subjective, we cannot fully understand another person’s inner experience.
This has implications for interpreting behavior, thoughts, and feelings across individuals.

The speaker mentions the film Silence of the Lambs as an example of fear and perception:
- "Raise your hand if you’ve ever seen Silence of the Lambs."
- "It’s gonna scare the shit out of you" (noting the strong language used).
- "You can’t understand half love that you’re awake" (colloquial phrasing used to illustrate difficulty in fully grasping others’ states).
- The suggestion to watch it in October to leverage its scare factor.

When assessing language capacity in a 3-year-old, you must hold in mind a broader pattern beyond isolated behaviors.
Observable patterns to consider: humming, stuttering, or other repetitive behaviors.
The assessor must know about the child’s overall behavior to determine typical vs atypical development.
Key question: What must be understood to decide if the child’s development is typical for our species?
The emphasis is on a species-wide model of typical development; the speaker notes that discussions about species norms recur "by two and by three" to frame expectations.
The speaker asks the audience if they have spent time with a 3-year-old and probes expectations about what a typical 3-year-old can do in speech and language.

To decide if behavior is typical or atypical, one must understand a model of what is typical for our species.
The phrase "by two and by three" signals recurring discussion about developmental benchmarks in early childhood and how they inform judgments of normalcy.
The emphasis is on comparing a child’s development to species-typical patterns, not just individual deviations.

The guiding question: "What are 40-year-olds by 40? What should you have in this place and in this time?"
Core expectation: some kind of stability.
The speaker identifies a key component of stability as having a job or career, and within that frame, a degree (education).

A job or career is expected, along with a degree.
The speaker emphasizes the need for interdependent, healthy, stable, long-term interdependent relationships with someone, regardless of family planning.
The phrase: "I see that you have created interdependent, healthy, stable, long-term interdependent relationships with someone, and I don't care if you decide to procreate or not."
The speaker wants to observe these qualities in various domains of life, not just romantic partnership.

The speaker highlights different domains where interdependence and care should be evident:
- Long-term friendships
- Care for parents and siblings
- Long-term romantic relationships
The speaker explicitly states that marriage is not a necessary condition for stability, though an interest is shown if someone has never been married.
A question is raised about whether someone has had long-term cohabitation as an indicator of stability: "Have you at least had long-term cohabitation? I'm looking…" (cut off in transcript)

The content links developmental norms to real-world life trajectories (work, education, family, and caregiving).
It highlights how social expectations shape assessments of individuals (clinical, educational, or sociocultural contexts).
It also reflects on ethical considerations: recognizing the diversity of life paths (e.g., not everyone will or should conform to a single life script such as marriage or procreation).

The impossibility of fully knowing another person’s consciousness invites humility in judgment about others’ experiences.
Assessments should be informed by species-typical development while respecting individual variation and life choices.
The emphasis on interdependence underscores the social nature of human well-being and the value of stable relationships and caregiving networks.

Links to developmental psychology: typical vs atypical development across early childhood and adulthood.
Links to social psychology: functioning within a social environment; impact of relationships on stability and well-being.
Real-world relevance: guiding expectations for education, career planning, and relationship-building in adulthood.

Consciousness is inherently subjective; full inner experiences cannot be fully known by others.
In developmental assessment, rely on a model of species-typical patterns and clear behavioral indicators.
By age 40, stability is expected across multiple life domains: work, education, and long-term relationships, with flexibility regarding family structure.
Long-term cohabitation and interdependent relationships serve as indicators of stability and health in a person’s life.
Ethical practice requires respect for diverse life choices and careful interpretation of life milestones within cultural and individual contexts.

"Is my red your red?" (subjective perception)
"You can’t understand half love that you’re awake" (limitations of understanding others’ inner states)
"Two and by three" (developmental discussion benchmarks)
"Interdependent, healthy, stable, long-term interdependent relationships" (relationship quality metric)
"Have you at least had long-term cohabitation?" (stability indicator)
"I don’t care if you decide to procreate or not" (acceptance of diverse life choices)
